Definitions

  • the present invention relates to the field of modular platforms of an electric motor vehicle chassis and more particularly to cooling modules for such modular platforms.
  • modular chassis platforms for an electric motor vehicle.
  • Such modular platforms such as those known from the document US10919575B1 or Dan Mihalascu's article "Israeli Startup's Next-Gen EV Platform Wants To Reinvent The Wheel” and published at: https://www.carscoops.com/2020/2017israeli-startups-next-gen-ev-platform-wants-to-reinvent-the-wheel/ , include in particular the batteries, the electric power train as well as the cycle part, in particular the wheels, the braking system and the suspension of the motor vehicle.
  • electric power train of the motor vehicle we mean more precisely the electric power as well as the electric motor(s) of the motor vehicle.
  • Such a modular platform is used in order to have a single platform, grouping together most of the propulsion, power supply and electrical storage components on which various passenger compartments and bodies are installed, corresponding to different models of motor vehicles.
  • Thermal management devices generally include a cooling module with at least one heat exchanger intended to be crossed by an external air flow. This cooling module is one of the largest components of the thermal management device. It is therefore difficult to integrate them within such a modular platform in which the free space is reduced while maintaining a heat exchange surface allowing efficient operation of the thermal management device.
  • One of the aims of the present invention is therefore to at least partially remedy the drawbacks of the prior art and to propose a modular platform with improved integration of a cooling module.
  • the present invention therefore relates to a modular platform of an electric motor vehicle chassis, said modular platform comprising the batteries as well as the electric power train of the electric motor vehicle, said modular platform comprising an upper floor and a lower floor between which is arranged at least one cooling module intended to be crossed by an external air flow, said cooling module comprising at least one heat exchanger, intended to be crossed by the external air flow, and a first collector housing attached to said heat exchanger, said first collector housing forming a volute within which a tangential turbomachine extends, the first collector housing comprising a first open end facing the heat exchanger and a second open end at the end of its volute, the cooling module being arranged so that the second open end of said cooling module faces one or other of the upper or lower floors of the modular platform, said upper or lower floor comprising an opening facing the second open end of the cooling module.
  • the second open end of the cooling module faces the lower floor of the modular platform, and in that said lower floor comprises an opening opposite the second open end of the cooling module.
  • the second open end of the cooling module is attached to the opening so that the edges of said second open end are in sealed contact with the edges of said opening.
  • the opening includes a protective grille.
  • the opening comprises a flap movable between an open position and a closed position of said opening.
  • the shutter is a shutter controlled by an actuator.
  • the shutter is a passive shutter comprising a device for returning it to the closed position.
  • certain elements or parameters may be indexed, such as first element or second element, as well as first parameter and second parameter, or first criterion and second criterion, etc.
  • it is a simple indexing to differentiate and name elements or parameters or criteria that are close, but not identical. This indexing does not imply a priority of one element, parameter or criterion over another and such names can easily be interchanged without departing from the scope of this description. This indexing also does not imply an order in time, for example, to assess this or that criterion.
  • placed upstream means that one element is placed before another in relation to the direction of circulation of a fluid.
  • placed downstream means that one element is placed after another in relation to the direction of circulation of the fluid.
  • FIG. 1 shows a modular platform A of an electric motor vehicle chassis.
  • This modular platform A includes in particular the batteries B, the electric power train as well as the cycle part of the motor vehicle, in particular the wheels, the braking system and the suspension of the motor vehicle.
  • power train The electrical system of the motor vehicle refers more precisely to the power electronics as well as the electric motor(s) of the motor vehicle.
  • Such a modular platform A is used in particular to have a platform on which various passenger compartments and bodies can be installed.
  • the modular platform A comprises a thermal management device comprising one or more heat transfer fluid circuits (not shown).
  • the thermal management device more particularly comprises different modules fluidically connected to each other in order to form the different heat transfer fluid circuits.
  • the thermal management device thus comprises a first module M1 as well as a second module M2 which comprise components such as heat exchangers, coolers, valves, pumps and compressors forming heat transfer fluid circulation circuits for thermal management.
  • the thermal management device also comprises a cooling module C intended to be crossed by an external air flow 500.
  • the cooling module C comprises in particular at least one heat exchanger C40 also intended to be crossed by the external air flow 500.
  • This cooling module C is intended to be integrated within the modular platform A, preferably in the front part of the modular platform.
  • the cooling module C comprises a heat exchanger C40 and a first collector housing C41 attached to said heat exchanger C40.
  • the first collector housing C41 forms a volute with a first open end C41a arranged opposite the heat exchanger C40 and a second open end C41b at the opposite end of the volute.
  • the cooling module C also comprises at least one tangential fan, also called a tangential turbomachine C30, configured to generate the external air flow 500, for example when the motor vehicle is stopped or when it is at a low speed.
  • the tangential turbomachine C30 comprises a rotor or turbine (or tangential propeller) C28.
  • the turbine C28 has a substantially cylindrical shape.
  • the turbine C28 advantageously comprises several stages of blades (or vanes).
  • the turbine C28 is rotatably mounted around an axis of rotation Cy, for example parallel to the plane formed by the heat exchanger C40 and extending across its width.
  • the turbine C28 is more particularly arranged within the volute formed by the first collector housing.
  • the C30 tangential turbomachine is thus compact.
  • the use of such a C30 tangential turbomachine allows in particular that the external air flow 500 is equal over the entire surface of the at least one C40 heat exchanger.
  • such a C30 tangential turbomachine allows space savings
  • the C30 tangential turbomachine may also include a C31 motor configured to rotate the turbine.
  • the C31 motor is, for example, adapted to drive the turbine in rotation at a speed between 200 rpm and 14,000 rpm. This makes it possible, in particular, to limit the noise generated by the C30 tangential turbomachine.
  • the tangential turbomachine C30 is configured to operate in suction mode, i.e. it draws ambient air so that it passes through the heat exchanger C40 and is discharged through the second open end C41b of the volute.
  • the tangential turbomachine C30 can operate in discharge mode, i.e. blowing air from the second open end C41b of the volute towards the heat exchanger C40.
  • the cooling module C may also comprise a second collector housing (not shown) attached to the heat exchanger C40 on its face opposite that comprising the first collector housing C41.
  • This second collector housing may comprise an opening in order to allow the external air flow 500 to pass.
  • This opening may comprise a closure device (not shown) movable between a first so-called open position and a second so-called closure position.
  • This closure device is in particular configured to allow the external air flow 500 to pass through said opening in its open position and to close said opening in its closure position.
  • the closure device may be in different forms, such as for example in the form of a plurality of flaps pivotally mounted between an open position and a closed position. These shutters are preferably mounted parallel to the width of the cooling module C. However, it is quite possible to imagine other configurations such as shutters mounted parallel to the height of the cooling module.
  • the shutters can be flag-type shutters but other types of shutters such as butterfly shutters are quite possible.
  • the modular platform A comprises an upper floor A1 and a lower floor A2 between which the cooling module C is arranged.
  • upper floor A1 is meant here an upwardly oriented floor, on which is intended in particular to be installed a bodywork and a passenger compartment.
  • the lower floor A2 forms the underbody of the modular platform A and faces the ground.
  • the modular platform A may also include a grille A42 or air openings A42, connecting the two floors A1, A2 facing the cooling module C.
  • the cooling module C is more particularly arranged between the upper floor A1 and the lower floor A2 so that the second open end C41b of the cooling module C faces one or the other of the upper floor A1 or lower floor A2.
  • the upper floor A1 or lower floor A2 facing the second open end C41b comprises an opening A45 opposite said second open end C41b of the cooling module C.
  • the external air flow 500 can circulate directly between the second open end C41b and the opening A45 in either direction depending on whether the tangential turbomachine C30 operates in suction or discharge mode. This makes it possible to isolate the external air flow 500 from the other components of the thermal management device present within the modular platform A, between the upper floor A1 and lower floor A2.
  • the cooling module C is preferably arranged so that the second open end C41b of the cooling module C faces the lower floor A2 of the modular platform A. It is thus the lower floor A2 which has the opening A45 opposite the second open end C41b. In suction, the external air flow 500 is thus evacuated by the second open end C41b of the cooling module C under the modular platform A.
  • the second open end C41b of the cooling module C is preferably attached to the opening A45 so that the edges of said second open end C41b are in sealed contact with the edges of said opening A45.
  • the A45 opening can include a protective grille (not shown) in order to limit any debris or projections from entering via the A45 opening.
  • the opening A45 may comprise a flap A46 movable between an open position and a closed position of said opening A45.
  • This flap A46 may for example be a flag or butterfly type flap.
  • the flap A46 may be a shutter controlled by an actuator (not shown) in order to move from one position to another as required.
  • the flap A46 may also be a passive flap comprising a return device (not shown), for example a spring, bringing the flap A46 into the closed position by default.
  • a return device for example a spring
  • the thermal management device also comprises a heating, ventilation and air conditioning device D intended to be crossed by an internal air flow 400 intended for a passenger compartment.
  • a heating, ventilation and air conditioning device D is illustrated in figure 3 .
  • the heating, ventilation and air conditioning device D comprises in particular, within a housing, a cooler D2, intended to cool the internal air flow 400, a heat exchanger D3, intended to heat the internal air flow 400, and a ventilation means D1 configured to generate the internal air flow 400.
  • the cooler D2 and the heat exchanger D3 are in particular intended to be connected to the heat transfer fluid circuits of the thermal management device.
  • the heating, ventilation and air conditioning device D may also comprise an electric heater D4 intended to additionally heat the internal air flow 400.
  • the heating, ventilation and air conditioning device D may in particular be arranged outside the modular platform A, for example within a passenger compartment installed on said modular platform A.
  • the thermal management device comprises a connection interface I (see figure 1 ) intended to allow the fluid connection of the heating, ventilation and air conditioning device D to heat transfer fluid circuits and to the elements of the thermal management device arranged within the modular platform A.
  • the thermal management device finally includes a BAT heat exchange interface with the B batteries.
  • the BAT heat exchange interface is notably arranged within the modular platform A and connected to the heat transfer fluid circuits of the thermal management device.
